Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting devices, specifically a circulating sandblasting device for thermal spraying. Background Technology

[0002] When spraying coatings onto a workpiece surface, sandblasting is a process that uses the impact of a high-speed abrasive jet to clean and roughen the substrate surface in order to improve the surface finish and roughness, remove impurities and rust residues left from machining, and prepare for the adhesion of subsequent paints or other coatings. Powered by compressed air, a high-speed jet propels the abrasive material at high speed onto the workpiece surface, altering its appearance or shape. Due to the impact and cutting action of the abrasive, the workpiece surface achieves a certain degree of cleanliness and varying roughness, improving its mechanical properties. This enhances the workpiece's fatigue resistance, increases adhesion between the abrasive and coating, extends coating durability, and also facilitates paint leveling and decoration.

[0003] However, existing sandblasting equipment still has some problems in use:

[0004] Traditional sandblasting involves blasting each workpiece individually in a separate blasting booth. These booths are space-consuming and use large quantities of sand, leading to significant waste if not recycled. Individual recycling is labor-intensive and generates dust, which can negatively impact health. Many factories lack dedicated blasting booths due to space constraints, severely limiting the effectiveness of traditional sandblasting methods. Therefore, an integrated sandblasting recycling system is needed.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing sandblasting equipment. Utility Model Content
